Abstract
Provided is a method for analyzing the metal impurity content that includes passing water to be analyzed through a monolithic organic porous anion exchanger, thereby allowing the monolithic organic porous anion exchanger to capture metal impurities in the water to be analyzed; passing an eluent through the monolithic organic porous anion exchanger which has been allowed to capture metal impurities in the water to be analyzed, to collect an effluent, thereby obtaining a collected eluent containing metal impurities in the water to be analyzed eluted from the monolithic organic porous anion exchanger; and measuring the content of each metal impurity in the collected eluent.
